- PLow AND CULTWATR FRAME.

SPECIFICATION forming part of Letters Patent No. 283,394, dated .August21, 1883. Application filed March 30, 1853. (No model.)

To all whom it mafyconcerb:

Be it known that I, FRANK A.. HILL, of Benicia, in the county of Solanoand State of California, have invented a new and useful Improvement inPlow and Cultivator Frames; and I do hereby declare that the followingis a full, clear, and exact description ofthe same.

'means for connecting the plows or shovels.v

f which thus connects it to the frame.

My invention relates to an improved manner of and means for adjustingthe frame of a gang plow or cultivator vertically; and the object oi'the invention is to connect the framework by adjustable arms to a singleoperatinglever, so that the front-and rear ends ofthe frame may besimultaneously adj usted by one man'at one operation.

The Ainvention consists in combining with the frame-work andcarrying-wheels an operating-lever and adjustable connections, in themannernow to be more fully described.

In the drawings, Figure 1 is a side elevation ofthe earryingwheels,frame, and operating mechanism. Fig. 2 is a plan view.

The frame-work is represented in the drawings at 1. It is preferably oftriangular form, as shown in Fig. 2, and is provided withthe ordinaryhorse-attaching devices, and with .Iournaled in bearings in the forwardend of the frame is an axle, 1S, which is cranked out-- side theframe-work at both ends, as shown at 8 4. On one end of the axle ismounted the wheel 15. The caster-wheel 17 is journaled in bearings inthe lower end of a hanger or standard, 9, which is free to turnhorizontally in a box, 1), secured to the framework, and thus permitsthe caster to turn freely. The rear supporting-wheel, 16, is j onrnaledin bearings in a vertically-adjustable standard, 8, which slidesin asuitable guide in the main frame, as shown in Fig. 1. The operating-le-vver 6 is pivoted to a standard or strap, 12, The end of the lever issecured adj ustably to the strap by means of a pin adapted to engagewith any one of a series 0i' holes in the stra-p. Gonnected to the lever6 is an arm, 11, the lower end of which is secured to the crank 4 of theaxle 18. The sliding standard 9 of the caster is directly connected tothe lever 6 by a swivelcap, 5, which permits the said standard to slidefreely in the box 10, and also to turn.

They rear wheel, 16, is connected to the lever 6 by means of aconnecting arm or lever, 7. The lever 7 is adjnstably pivoted to therear end of the lever 6 by a strap or link, 13. Such lever is attachednear its middle to the sliding standard 8, in which the wheel 16isjournaled. The lever 6 is provided with a spring-pawl,of

the teeth of a rack, 14, and holds the lever in any position desired.

It will be evident now, from the description and drawings, that if thelever 6 be elevated duce a ,simultaneous elevation of the three wheelsand a relative depression of the whole frame. The cranked axle will turnin itsbearings, while the standards 8 and 9 will slide upward in theirboxes or guides. standards and the lever 7 can be so adjustedrelatively, as provided for, that the raising of the lever will produceany degree of inclination in the frame that may be desired, or that atany height.

I do4 not confine myself to the precise man ner of attaching the leversand arms, as any arrangement for adj ustably securing such parts ployed.

Having thus fully described my invention, what I claim as new is- 1. Thecombination, with the frame and the cranks, the arm connected to suchaxle, and the lever 6. l

2. The combination of the frame, the lever 6, the cranked axle havingthe wheel 15 jouring standard, and the wheel 16, connected to the lever6 by `the arm 7.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
